COMPOUND WHICH FORMS AN EMULSION WITH WATER TO BE APPLIED TO THESURFACES 0F ROADS OR OTHER PLACES.

Specification of Letters Patent.

Patented April 24, 1906.

To all whom it may concern.-

Be it known that I, EDWARD HARDOASTLE, a subject of the King of GreatBritain, residing at St. Petersgate Mills, Stockport, England, haveinvented a new and useful compound which forms an emulsion with water tobe a plied to the surfaces of roads or other places or the purpose ofpreventing the formation of dust and of allaying it, (for which I haveobtained a atent in Great Britain, No. 14,239, dated July 11, 1905,) ofwhich the following is a specification.

The formation of dust on the surfaces of roads is well known to be anuisance and a dan er to the health of the community.

y invention has for its object the manufacture of a fluid by which pitchor asphaltum can be brought into mixture with water, so as to enable itor them to be sprinkled or spread over such roads to prevent the dustforming or arising. This is accomplished b the itch or asphaltum beingleft on the roa sur ace agglutlnating the particles when the water hasevaporate therefrom. All roads, especially those paved with wood, arerestinglaces for those disease germs which arise om animal-droppings. heaseptic properties of this preparation have a remedial action thereon.

My said compound consists of the followmg:

I take of- 1. (a) Coal-tar creosote, fifty gallons; (6) coal-tar pitch,one hundredweight; (a) resin, two hundredweight, one gram, 0 pounds.These I mix together and melt by heat until solution is effected.

I'also take of-- 2. Caustic soda or caustic potash, twentyeight 'ounds,and dissolve it in eighteen gallons 0 water.

The above proportions, however, may be varied accordm to circumstances.

I then pour t e latter solution (2) into the former mixture (1) andagitate until the whole is completely combined. This improved compoundforms an emulsion when mixed with water so as to deposit the pitch or ashaltum upon the road-surface.

at I claim, and desire to secure by Letters Patent of the United States,is

The herein-described compound consisting of coal-tar creosote andresinate of soda holding pitch or asphaltum in solution which forms anemulsion with water, for the purpose of preventing the formation of dustand allaying it.
